Xenon Weathering

Atlas – The performance benchmark for xenon weathering testing instruments

  • Overview +


    Atlas has been designing and manufacturing material weathering test equipment for more than 100 years, initially starting with carbon–arc lighting technology inside. Since the introduction of the first xenon-arc based weathering instrument – the Xenotest 150 – xenon-arc instruments, also known as Weather-Ometers®, Xenotest® or SUNTEST®, have become indispensable tools for new product development and quality control.

    Accelerated testing with xenon weathering instruments provides multiple benefits. Most importantly, they help you minimize the risk of premature product failure, deliver fast stability screening of new materials / formulations, optimize the use of costly additives, and provide comparison against competition. Since the introduction of its first xenon weathering instrument, Atlas has continuously set performance benchmarks with state-of-the-art technology.

  • Suntest Family +


    Today, the Atlas SUNTEST Series is based on air-cooled xenon technology with static horizontal exposures. SUNTEST benchtop models have become industry standards in the cosmetic and pharmaceutical industry. Furthermore, SUNTEST XLS+ and XXL+ come in practical whenever 3-D specimens become too large or difficult to be exposed inside rotating rack instruments.
